I've been looking at this triangle (SPX index) for the past few days also but it doesn't seem to me that it was broken today -- i just see it at the lower support line (at least that's the way it looks to me on the daily chart I'm looking at..)
(i assume you are talking of the triangle from 1245.9 top, 1201.1 bottom, 1243.1 top, 1205.3 bottom, 1233.3 top, today's low 1214? )
